BS 812-111:1990

This standard BS 812-111:1990 Testing aggregates is classified in these ICS categories:

• 91.100.15 Mineral materials and products

This Part of BS 812 describes methods for the determination of the ten per cent fines value (TFV) of aggregates which give a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.

Two procedures are described, one in which the aggregate is tested in a dry condition and the other in a soaked condition.

The methods are applicable to both weak and strong aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve. For other size fractions, a recommended method is described in appendix A.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
